Mini-comp premise too complex for you?  Write up just a scene or two from a 
game based on that premise.  No scene is too small!

So, for example, you could write up the scene where the protagonist is
simply obtaining one of the items on the list.  Or one where they race
an NPC to obtain something.  Or just a menu-based conversation where you
have to convince another relative to work with you.  Or whatever.  Have
fun, and be creative!
